Mmfp 1003 08 Oil System Upgrade Cnc Ported Aluminum Heads

Trick Flow Specialties also offers a number of different as-cast and CNC-ported aluminum heads for the small-block (302 and 351W) Fords. We chose a set of Twisted Wedge Track Heat 185 cylinder heads (CNC-ported). The 185cc intake ports flowed just over 300 cfm, more than enough to support our 347 test mule.
